Title: Heater controller for flowmeter
Inventor: OISHI YASUHARU
IPC: G01F1/68
Filed: 1990-05-31
Abstract: PURPOSE:To achieve a higher accuracy by controlling a temperature of a resistance for a heater by controlling a positive temperature coefficient with respect to an ambient temperature to render flat a temperature characteristic of sensitivity of a sensor. CONSTITUTION:A reference resistance 2 is connected in series to a resistance 3 and a voltage at a midpoint (a) of the resulting series circuit is applied to one input side of a differential amplifier 7 while the other input side thereof is earthed through a resistance 4. With such an arrangement, when a resistance value of a resistance 1 for a heater is represented by RM, a resistance value of the reference resistance 2 by RR, and a resistance value of the resistance 3 by Ra, almost a constant current flows through the resistance 2 with Ra>R> RR. As a result, a potential rises at a connection point (a) with a rise in an ambient temperature and a temperature of the resistance 1 rises by a temperature coefficient of 1+alphaT0. This enables the correction of a drop in sensitivity as caused by a temperature rise of the sensor. In the temperature coefficient, alphais the temperature coefficient and T0 the ambient temperature.
